In addition to emailing your four Ad Hoc provisioning profiles to
support@owncloud.com, you must also include your P12 certificate. To create
this, return to Keychain Access on your Mac computer and find your private key
that you created at the beginning (see
Create Certificate Signing Request).

Enter any name you want, the location you want to save it to, and click
Save.

In the next screen you have the option to enter a password. If you put a
password on your P12 certificate you will have to include it when you send your
certificate and provisioning profiles to support@owncloud.com. Click OK.

On the next screen you must enter your login keychain password, which is your
Mac login password, and click Allow.

Now your new P12 certificate should be in the directory you saved it in.

You have now completed all the necessary steps for signing your branded iOS
app. The next step is to build your app with the ownBrander app on
https://customer.owncloud.com.
